To all whom it may concern:

Be it known that l, HAnoLn S. BAILEY, a citizen of the United States, residing at Barker, in the county of Niagara and State of New York, have invented new. and useful Improvements in Governors for Gas En- 'gines, of which the following is a specification.

This invention relates to a governing device for internal combustion engines.

@ne of its objects is to provide an improved automatic governor of this character which is very sensitive and e'iiicient in operation, which is simple and durable in construction and which can be manufactured at a moderate'cost.

A further object is to produce adevrce, which, while governing the amount 0% mixture admitted to the combustion chambers of the engine, will also efi'ectively 'atornize or break up the fuel and intimately lIllX it with the proportionate amount of air.

In the accompanying drawings:

Figure 1 is a sectional elevationof a governor constructed in accordance with my 1nvention. Figure 2 is a horizontal section on line 2-2, Fig. 1. Figure 3 is a fragmentary sectional elevation of a modified form of the improvement. Figure 4 is a horizontal section thereof, on line M, Fig. 3. Figure 5 isa view, similar to Fig.3, showi ng'another modification'ot gthe device. Figure 6 is a horizontal section thereof, on line 6-6,

imilar characters of reference indicate corresponding parts throughout the several views.

This improved governor is of the type which is responsive to or controlled by the suction of the e 'ne for admitting more or less of the explosive charge thereto dependin on its speed and load.

lieferrin to Figs. 1 and 2, the governor is preferab y located in the intake manifold 10 of the engine whose lower or inlet end 11 communicates with a source of gas supply,

while its upper or outlet end 12 communicates with the engine cylinder (not shown). Near its upper end the manifold is provided with a mixture outlet port 13, while in its lower end it is preferably provided with an opening 14 arranged in line with said port and normal! closed b a cover plate 15 fastened to sai manifol by bolts 16 or other up ropriate fastenings.

isposed centrally in the manifold or 25, 26, 27 which, b

1. A spring 22 surrounding the lower exposed end of the valve stem and confined between the cover plate and an adjusting nut 23, tends to resist movement of the valvedisk out of said normal position.

Mounted on the stem 18 between the valve plug 17 and the cover plate 15 are a number of sets of governing disks or baflles 24,

preference, are alternately large and sma l, the large disks 24 and 26 being substantially of the same diameter as the manifold 10. hese disks are held in spaced relation by space-sleeves 28 or other appropriate means. The suction produced by the engine acts on these disks to raise the valve plug 17 toward its. port 13 and decrease the amount of fuel charge delivered to the combustion chamber.

The large disks 24 are preferably provided with a plurality of openings 29 which are located opposite the solid small disks 25. By this arrangement, the en 'ne suction is more efi'ective on the severa disks to obtain a prompt and sensitive action of the throttle-valve. Aside from this function, these disks also serve to retard the flow of the fuel through the intake manifold. causing it to be thoroughly atomized or broken up and intimately mixed. During its passage through the manifold, the fuel ascends through the openings 29 of the lowermost large disk 24 then impinges against the adjac'ent solid disk 25, by which it is broken up and deflected laterally. The "fuel thence passes through the annular space between the edge of said solid disk and the wall of the manifold, thence through the openings of the next large disk, and against the next solid disk 27, by which it is again broken up and deflected, finally ascendin around the edge of the last-named disk an passin into the engine cylinder. Two sets of dis are shown in the drawings by way of illustration, but a greater or less number may obviously be employed.

In order to prevent the throttle valve 17 from entirely closing the port 13 and thus completely shutting off the admission of fuel to the combustion chamber of the engine, said valve is preferably slightly smaller than its port, to leave a narrow passage between the wall of the port and the edge of the valve for the sup 1y of a minimum amount of fuel for" id ing purposes, even when the valve is closed to maximum.

The valve stem 18 is provided between the cover plate 15 and adjusting nut 23 with a stop collar 30, asshown by dotted lines in Fig. 1, which stop is' adapted to abut.

against said plate to limit the maximum closing movement of the throttle valve.

When the engine is traveling at high speeds, the resulting increased suction causes the atmospheric pressure to act on the governor disks 24-27, thus moving the throttle valve 17 upward into its wort 13 to lessen the efie;tive area of the latter and decrease the amount of fuel delivered to the engine. It follows that the engine speed is likewise reduced. Vihen running at low speeds. the spring 22 overcomes the less powerful suctlon produced by the engine, thus resisting movement of the throttle valve out of its wide open pesition and admitting a .full charge of fuel to the engine. It will be understood that by adjusting the tension of the spring 22, through the medium of the nut 23, the throttle v'alve may be regulated to automatically close at any desired redetermined engine speed.

In t e modification shown in Figs. 3 and 4, the large disks 31, 33, similar to the disks 24 and 26 of the previousl described construction. are provided wit comparatively long radial slots or passages '32 extending inwardly from their outer edges instead of perforations, while the small disks 34-435 are solid, as in the preferred embodiment of the invention.

Instead of employing alternately large and small disks for each set, they may be made of one size, as shown in Fi s. 5 and 6. In this instance, each of the disks 36 has long radial slots or passages 37 arranged out of register with the slots of adjacent disks; or in other words, the slots of each disk are located opposite the solid portions of the next disk, so that the fuel ascending through memes port, a valve stem slidable in said conduit.

a throttle valve mounted on said stem and movable toward and from said outlet port,

and a plurality of battle-disks mounted on said stem and arranged in sets, some of said disks having fuel-passages and others having solid ortions ocated opposite the passages of t 1e first-named disks.

2. A device of the character described, comprising a fuel conduit having an outlet port, a valve stem slidable in said conduit. a throttle valve mounted on said stem and movable therewith toward and from said outlet ort, a series of spaced disks mounted on said stem in rear of said valve and arranged in sets, one disk of a set having fuelpassages and the companion disk having solid portions located opposite the passages of the first-named disk, and means for resisting movement of said valve toward its closed position.

3. A device of the character described, comprising a fuel conduit having an outlet port, a valve stem slidable in said conduit, :1 throttle valve mounted on said. stem and movable therewith toward and from said outlet port, and a series of alternately-arranged large and small disks mounted on sai stem, the small disks being solid and the large disks being provided with fuelpassa es.

4. device of the character described. comprising a fuel conduit having an outlet port at one end and an ripening in line therewith at its opposite en a coverplate a)- plied to said opening, -a gvalve stemslidabiy mounted in said plate, a throttle valve fixed to the inner end of said stem and movable therewith toward and from said outlet port, and a series of disks mounted on said stem between the valve and the coverplate and arranged in sets, one disk of a set having fuel-passages and the companion disk having solid portions located opposite said passages.
